The storage tip comes from Zero Waste Week who is on a mission to “reduce salad waste” amongst other food waste.
“I can help you keep those pesky salad leaves fresher for longer, which means your budget will stretch further and you can get a high five from Mother Nature for doing your bit,” they wrote.
There was a picture of salad leaves that were “pretty fresh”. In fact they were “ten days old”.
As for how the salad remained unwilted, they revealed: “I simply separated the leaves when I got them home and put them into a container of water.
“That container was kept in the fridge and hey guess what? No wilting salad, even after ten days”.

There wasn’t details about whether the water was changed regularly, or the storage container the lettuce was kept in. But Taste Great Foodie shared the same storage tip with more detail.
1. Soak and wash lettuce, either cored with leaves pulled apart, or as a whole.
2. Put into an airtight container submerged in water.
3. Remove leaves when needed or use entire lettuce.
4. You can change the water every three days so the lettuce lasts longer.
4. Lettuce stays fresh anywhere from 10 days to a whole month.
Can bacteria form on the lettuce while submerged in water?
The experts said “mould can’t grow on something fully submerged in water, especially for a two to four week span”.
To ensure the lettuce is really clean, soaking it in vinegar and thoroughly washing it before submerging it “can lessen the risk of bacteria”.
